Which network type is designed to be wireless and used for guest access in small businesses?

• A. LAN
• B. WLAN
• C. SAN
• D. CAN

Answer: (B)

Wireless connectivity for guests in a small business is provided by a WLAN, a Wireless Local Area Network. This setup is designed to cover a local area with Wi‑Fi, letting visitors connect their devices to the internet while keeping the internal network protected. In practice, you’d deploy wireless access points across the space, broadcast guest SSIDs, and often use features like captive portals and separate guest VLANs to isolate guest traffic from internal resources.

A LAN is the broader local network concept and can be wired or wireless, but the term doesn’t specify wireless guest access. A SAN is a Storage Area Network, focused on high-speed storage networking rather than end-user guest access. A CAN, or Campus Area Network, extends across multiple buildings and is a larger-scale network that isn’t specifically about providing guest wireless access in a small business.
